I recite the remembrances and entrust my husband to Allah, so why do I not feel their preservation and why do I experience worry and sorrow?

Allah Almighty does not lose what is entrusted to Him. The Messenger of Allah, peace and blessings be upon him, said: "Indeed, if Allah is entrusted with something, He preserves it." And he, peace and blessings be upon him, used to say to those he bid farewell: "I entrust to Allah your religion, your trust, and the consequences of your deeds." Allah has promised to answer, but answers take multiple forms, and their impediments must be absent. The failure to receive an answer is due to the servant himself because of an impediment, and the effect of remembrance (dhikr) and supplication (du'a) varies according to certainty, uprightness, and the wisdom of trials. Allah preserves the believer who observes the limits of his religion with various types of preservation.
